For a Sangfor NGAF deployment with 4 bridge pairs, the minimum number of physical ethernet ports you'll need depends on several factors:

    Network Traffic Flow: The number of physical interfaces required depends on how your network traffic flows and how you plan to use the Sangfor NGAF for tasks like routing, inspection, and management.

Here's a breakdown of possible scenarios:

    Basic Routing and Inspection (Minimum):
        If the Sangfor NGAF will only perform basic routing and inspection duties, you might be able to get by with 6 physical ports. This would involve:
            2 ports for the bridge pair interfaces (incoming and outgoing traffic).
            2 ports for the internal LAN (trusted and untrusted zones).
            1 port for management access.
            1 optional port for redundancy (depending on your needs).

    Advanced Routing and Security Features (More Likely):
        In most cases, for a production deployment with advanced features like multi-WAN links, DMZ, or redundancy, you'll likely need more than 6 physical ports. Here's a possible breakdown:
            4 ports for the bridge pairs (2 pairs).
            2 ports for the internal LAN (trusted and untrusted zones).
            2 ports for separate WAN connections (if using multi-WAN).
            1 port for DMZ (if needed).
            1 port for management access.
            1-2 optional ports for redundancy on critical interfaces.

Considering the above scenarios, options 3 (10 ports) or 4 (11 ports) would be more suitable for a Sangfor NGAF deployment with 4 bridge pairs, especially if you plan to use advanced features or want redundancy.

Here are some additional recommendations:

    Consult Sangfor Documentation: Refer to the Sangfor NGAF deployment guide for your specific model for the recommended number of ports based on your desired configuration.
    Network Design Considerations: Plan your network traffic flow and consider how the Sangfor NGAF will be integrated into your network. This will help determine the specific number of ports needed for different purposes (WAN, LAN, DMZ, etc.).

By carefully considering your network requirements and consulting the Sangfor documentation, you can determine the optimal number of physical ethernet ports needed for your 4-bridge pair Sangfor NGAF deployment.
